Superhero crime-fighters Lyra and Bon-Bon discover their Cutie Marks have been switched. And that's only the start of their problems. Crime-fighting organisation M.A.R.E is under threat from King Sombra. But King Sombra's dead... isn't

The Cutie Mark Inspector visits Ponyville to conduct a cutie mark review of the townsfolk. When it transpires that every pony has been interpreting their cutie marks wrong, Ponyville is thrown into chaos.

The ponies are about to carry out Summer Shutdown and bring back winter. This does not sit well with a small breezie colony living in Applejack's orchard. Someone has to stop the ponies and save the world...

That's like us AMERICANS saying all British people equate coffee to black sludge.

Isn't it? If we tar our roads with marmite, don't you tar yours with coffee? Besides, coffee is banned from the shores of Britain under the dangerous foods act, due to its tendency to stop people having sexy accents by sticking their tongues to the roof of their mouths.

Marmite: Polarizing and quintessentially British savoury spread made from an unwanted by-product of the beer-brewing process which other nations would throw away. The fact that the British like to eat it demonstrates a classic British quality - resourcefulness. And willingness to eat something that looks and tastes like the contents of a smoker's lungs.

A torrent of Marmite fell straight down her throat. “BLAAAAAARGH!” Sweetie Belle screamed, vomiting it straight back up in some sort of black gungy fountain.

Showing two speakers in one paragraph for some reason despite it copy-paste saying there is a space between the two independent speakers. Looks like a format error on importing? *shrug*

Gawd, cheese outside of an aerosol can? That dude's just spreading discord EVERYWHERE!What a sicko.

And the roads did run with rivers of vomitus and the foals wept to see their fathers and mothers spread before them in the throes of agony. Lo, for the same nation that puts steak sauce on pancakes did attempt to spread their tastes far and wide and the ponies of Equestria did weep for their lack of maple syrup.

EDIT: I posted this BEFORE I read the story because yuck. After reading it, very apropos.
